ROTATORY ENERGY RECYCLING CONTROL DEVICE FOR HYDRAULIC EXCAVATOR
A rotatory energy recycling control device for a hydraulic excavator, comprising: an oil line selector valve (1), a direction selector valve (2), a sequencing valve (3), a one-way valve (4) and an overflow valve (5); two oil inlets of the oil line selector valve (1) are respectively connected to an opening A and an opening B of a rotary motor; an oil outlet of the oil line selector valve (1) is connected to an inlet of the direction selector valve (2); an outlet of the direction selector valve (2) is connected to an net of the sequencing valve (3); a drainage port of the sequencing valve (3) is connected to an oil tank; an outlet of the sequencing valve (3) and an net of the one-way valve (4) communicate with the overflow valve (5): the outlet of the one-way valve (4) is connected to an energy storage and utilization device; and an outlet of the overflow valve (5) is connected to the oil tank. One device can simultaneously achieve energy recycling from rotatory start and deceleration braking with fewer components and simplified piping designs.
